2 Technical information

Pull-up resistances R DAT and R CMD are included to prevent bus floating when no card is

inserted or when all card drivers are in high impedance mode.

The pull-up resistors and capacitors described in the above recommendation are integrated in the EMIF06-mSD02C3. This makes the EMIF06-mSD02C3 an easy "plug and play" solution to implement secured T -Flash, mini-SD and micro-SD card terminations.
